The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'status' parameter in the wpr_update_form_action_meta AJAX action in all versions up to, and including, 1.7.1056. This is due to insufficient input sanitization and output escaping, combined with a publicly leaked nonce that allows unauthenticated access to the AJAX handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AnalysisAI
Stored Cross-Site Scripting in Royal Elementor Addons WordPress plugin allows unauthenticated remote attackers to inject malicious scripts that execute in victim browsers. The vulnerability exists in all versions up to 1.7.1056 due to a publicly leaked static nonce that bypasses authentication checks for the wpr_update_form_action_meta AJAX endpoint. Combined with insufficient input sanitization on the 'status' parameter, attackers can inject persistent XSS payloads without authentication. EPSS data not provided; no CISA KEV listing indicates no confirmed widespread exploitation at time of analysis.
Technical ContextAI
This vulnerability affects the Royal Elementor Addons plugin (wproyal:royal_addons_for_elementor), a WordPress extension that enhances Elementor page builder functionality. The flaw is a CWE-79 (Improper Neutralization of Input During Web Page Generation) stored XSS issue in the form actions status management module. The vulnerable code path includes an AJAX handler (wpr_update_form_action_meta) registered in plugin.php that processes form metadata updates. The critical security failure is twofold: first, the nonce verification mechanism uses a static, publicly discoverable value rather than WordPress's built-in dynamic nonce system; second, user-supplied data in the 'status' parameter is stored in the database without proper sanitization and later rendered without output escaping. The WordPress plugin repository references show the vulnerable code in wpr-actions-status.php at lines 21 and 73, with the AJAX handler registration visible in plugin.php at line 613. The fix in changeset 3503219 addresses both the nonce weakness and input validation gaps.
RemediationAI
Immediately upgrade to Royal Elementor Addons version 1.7.1057 or later, which addresses both the nonce weakness and input sanitization issues per changeset 3503219 visible at https://plugins.trac.wordpress.org/changeset/3503219/royal-elementor-addons. Site administrators should access WordPress admin dashboard, navigate to Plugins → Installed Plugins, locate Royal Elementor Addons, and click Update Now. After patching, review form submission data and post/page content for suspicious JavaScript injection patterns (script tags, event handlers, data URIs) as existing malicious payloads will persist post-patch. If immediate patching is impossible, disable the Royal Elementor Addons plugin entirely until upgrade is feasible - partial mitigations like WAF rules are insufficient given the authentication bypass via leaked nonce. Disabling the plugin will break Elementor-dependent pages but prevents exploitation. For sites requiring continued operation, implement Web Application Firewall rules blocking requests to /wp-admin/admin-ajax.php with action=wpr_update_form_action_meta, though this may disrupt legitimate form functionality and does not address already-injected stored payloads. Audit user roles with form management permissions and review recent form submissions for anomalous content.
